Why ppl create cool threads just when I´m not looking !!? Er.. whatever...
There is no absolute concept of present, thats what relativity tells, for example, everything you look at is in the past(since light takes a time to arrive where you are), distant things(like stars) are more in the past than nearer things(like your pc). When we look at the sun, we are seeing what happened eight minutes before the present, and there is no way to know what happens in the sun right now in the present moment. As I told before everything you are looking at is in the past, the only present that exists to you is in the point where you are since its the nearer place from you. Simultaneity is relative, if there is two events A, and B, there could be one frame of reference where A happens first, one where B happens first, one where both happen at the same time, and even the separation in time between the events will vary.
Before time is contradictory, and there is no before time, but if you still want a way to comprehend it here is what I think... If we say that time is finite as I believe, I think the period "before" time... is not exactly a period.... lets call this place(the period before time) A. A can´t happen before the Big Bang, if it does, then A would be a period of time what implies that there would be time before time. This way time will be infinite. The best way to understand A for me is like something that is outside the time, I mean... A is not in the past or future, it not happened or is about to happen as things that exist in time.

I'm not really referring to Einstein, but don't worry- everyone has done that.

For me, the point you just made isn't the end of the debate, it's the beginning.
That particular answer always leaves me really frustrated, because it's not satisfactory (not criticising you, just the fact that the concept can't be expanded more fully).
In philosophical terms, what do we think happened before the Big Bang? Or even in scientific terms.

I think that before time makes no sense, "before" is a word that is defined inside time, it depends on time to exist. I´m not saying that this question doesn´t make sense or anything like this, but the subject that we are trying to comprehend is not exactly a period before time, since period and before are words that depend on time. To say that there is a period before time, is like to say that there is another time in which our time is inside it. So I think that a better way to comprehend it, is like a place outside time, not a period before time. Its interesting that if this place is outside time it never happened or is about to happen. I think that it would be like a concept or idea, for example, those are things outside time (they don´t happen, or are about to happen). I think that probably it is more than simply concepts, and ideas, but I can´t think of what more things it would mean.
